IntroductionWritten by experienced teachers and authors, Macmillan Education’s CSEC® Revision Guides provide a clear route to exam success. Inside this book you’ll find complete, concise revision notes on all key syllabus topics, in addition to practical advice on how to approach your revision and tackle the exams themselves, helping you to prepare effectively for your examinations.
Having reviewed the key points of each topic, you can refresh your knowledge and build your confidence with in-text practice questions, before moving on to sample practice exam papers at the end of the book. Questions are written in CXC examination style so that you will become familiar with exam wording and know exactly how to achieve your best possible grades.
Answers to questions are available online at www.macmillan-caribbean.com.
How to Use This Book
Each section begins with a checklist so you can rate your confidence in each topic
and prioritise your revision effectively.
Each section starts with a concept map showing key topics
and, crucially, how they link together. Does X cause Y? Does X run in tandem
with Y? Does X allow Y to happen?
At the end of each section you will have the opportunity to fill in your own blank concept map to check your understanding. It will
also provide a useful summary for last‑minute self‑testing.
Test Yourself with these quick fire questions to monitor your progress.
Revision Tips provide you with interesting ways to make sure you retain all of this information.
Reviewed Revised Mastered
You’ll find these checkboxes for each topic so you can track your learning and be confident you’ve covered everything thoroughly. Review the topic and return to your Student’s Book if there’s anything you don’t understand, then come back and revise the topic in this revision guide – and tick ‘Mastered’ when all of your answers were correct!
Tick the box that shows how confident you feel Yes Maybe NoSelf Check
Whenever you find a keyword highlighted like this, you can find out its meaning in the glossary at the back of the book.
Remember boxes contain handy nuggets of key information.
If you don’t understand these, go back to your Student’s Book
and refresh the topic.

Revision and Exam TipsThe content in this revision guide has been carefully written to make sure you have all of the key information needed for CSEC success at your fingertips. It has already been broken down for you into manageable chunks, based on the official CXC syllabus and exam structure.
Here are some tips to help you get the best out of this material:
■ Start preparing ahead of the exams so you can give yourself enough time to get through all your work.
■ Set long-term and short-term goals to help break up the work into manageable chunks. ■ Write out a revision plan to help you stay on track; make sure to include breaks as learning is much
more effective when spaced out over stretches of time. ■ Remove all distractions from your study area. ■ Make sure you have all the resources you need – this guide, a pen and extra paper. ■ Use practical memory aids where you can; make flash cards, and use tables and mind maps like the
ones in this guide. ■ Try explaining all of the key words to another person without looking at the glossary. ■ Test yourself and ask someone to test you. ■ Recognise your revision milestones using the self-check boxes provided.
In the exam:
■ Spend the first 10 minutes reading through the paper carefully, and work out a rough schedule to make sure you complete all the questions.
■ Read each question before trying to answer it. ■ Check your work and presentation carefully. ■ Make sure you understand what the questions mean, so you can apply your knowledge properly:
■ Analyse: study something in detail and identify characteristics of each piece of information ■ Assess: make a judgement based on the facts provided ■ Calculate: work out the value ■ Comment: give your opinion ■ Compare: give similarities ■ Contrast: give differences ■ Define: give the meaning ■ Describe: give the characteristics ■ Discuss: give the key points ■ Estimate: give a value based on rough working ■ Explain: give reasons ■ Identify: name/characterise ■ Illustrate: give examples ■ Justify: support your answer with evidence

Impact onorganisms
I can group living organisms found in a named habitat based on observed similarities and differences.I can classify organisms into taxonomic groups based on physical similarities.
I can carry out a simple ecological study using the most appropriate collecting and sampling methods.I can discuss the impact of the abiotic factors (soil, water, climate) on living organisms.
I can identify the relative positions of producers and consumers in food chains.
I can identify from each habitat a food chain containing at least four organisms.I can identify from each habitat: herbivore, carnivore and omnivore; and predator/prey relationships.
I can construct a food web to include different trophic levels.
I can explain the role of decomposers.
I can assess the special relationships among organisms.
